By Texas Instruments 158

TRF3765 Integer-N/Fractional-N PLL

Texas Instruments' TRF3765 is a wideband Integer-N/Fractional-N frequency synthesizer with an integrated, wideband voltage-controlled oscillator (VCO). Programmable output dividers enable continuous frequency coverage from 300 MHz to 4.8 GHz. Four separate differential, open-collector RF outputs allow multiple devices to be driven in parallel without the need of external splitters.

Features Applications
  • Output frequencies: 300 MHz to 4.8 GHz
  • Low-noise VCO: –133 dBc/Hz (1 MHz offset, fOUT = 2.65 GHz)
  • 13-/16-bit reference/feedback divider
  • Wireless infrastructure
  • Wireless local loop
  • Point-to-point wireless access
  • Wireless MAN wideband transceivers
